A motorcyclist with hematomas and tingling in his leg

: A 30-year-old man presented with recurrent hematomas and tingling in his left leg, caused by a large femoral neck osteochondroma that induced multiple muscle ruptures and compressed the ischiadic nerve. There were no radiological signs of malignant transformation and symptoms disappeared without intervention. Hence, we chose a 'wait and see' approach instead of surgical removal of the osteochondroma.
